UNITED STATES PATENT OFFICE.

SHELDON CANFIELD, OI DERBY, CONNECTICUT.

UMBRELLA AND PARASOL.

Specification of Letters Patent No. 18,086, dated August 25, 1857.

To all 'whom t may concern.'

Be it known that I, SHELDON CANFIELD,

of Derby, inthe county of New Haven and State of Connecticut, have invented a new and Improved Clamp for Umbrellas and Parasols, by which the ends of the stretchers are attached to the rods that support the canopy; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure l represents a part of an umbrella frame of the usual construction. X Y is a port-ion of the handle or staff. A B is one of the rods that support the canopy. C D is one of the stretchers, and at E is shown one of the clasps which I have invented.

Fig. 2 shows the upper side of the clasp E which was not shown in Fig. l.

Fig. 3 shows the form of the clasp E before the rod A B is inserted.

Fig. 4 is a view of the clasp and part of a stretcher attached to it in an inverted position.

The clasp E is made of a single piece of thin sheet metal so folded in the middle as to form on the under side of the clasp two flanges e and f each consisting of a double thickness of the sheet metal, (see Fig. The upper end of the stretcher C, D is attached to the clasp by means of a rivet m that passes through the flanges e and f, and through an eye at the end of the stretcher, (see Fig. 4.) The rib of the umbrella A B is placed in the upper part of the clasp and the edges of the clasp are bent over it as represented in Fig. 2. The clasp is secured from sliding on the rib by means of a rivet n passing through the sides of the clasp and through the ribs or by simply making indentations in the sides of the clasp penetrating into the rib.

Y The clasp may be made by hand or by a press or other machine adapted to the purpose. The sheet metal is first cut into strips of a width equal tothe length of the clasp. These strips are submitted endwise to the machine by the action` of which the metal is folded into a clasp of the form above described and represented in Fig. 3 and is severed from the strip at the same time.

lVhat I claim as my invention and desire to secure by Letters Patent isl. The form and construction of the clasp E herein described and represented in Fig.

3; it being made of a single piece of thin sheet metal so folded in the middle, either by a machine or otherwise, as to form on the under side of the clasp two flanges e and f each consisting of a do-uble thickness of the sheet metal.

2. I claim the clasp as applied to umbrellas and parasols.

I claim nothing else herein described as my invention.

SHELDON CANFIELD.
